can not contact SAC

[Royt]

Running unixware 7.1.1 with Stallion Easyserver/TruPort installed.

Having switched the easyserver units off/on a few times and then killing/restarting the TruPorts with sacadm I have finally ground to a halt.

# sacadm -l ... quite a long delay and then:-

# can not contact SAC

I am certain the problem can be cleared by rebooting but can anyone suggest a method of doing it WITHOUT the reboot?

Hi,

You can try to start again manualy the SAC with the command

# sacadm -p ttyserv -e

where ttyserv is the name of your port monitor

Remember that with pmadm you can admin individual ports.

Other way is to check in the inittab file the line that starts the SAC and run that command for yourself.

I Hope this can help


# man sac or man pmadm

Thanks JorGeVaL

The immediate problem with sac is solved by killing the sac pid. It then respawns and works normally.
The problem remaining is that we haven't managed to restart the TruPort entry which caused the sac problem in the first place. This still requires a reboot.

Hi Roy,

I dont know what is TruPort ? is that the name of the PotMonitor ? , like the ttymon ?

With sacadm you can stop and restart the daemon but i am just guessing that TruPOrt is the monitor.

TruPort is a Stallion Technologies multiport system. We have tried killing, restarting, removing and adding with sacadm with no effect. Each box runs 16 serial ports and the problem is at the box level so pmadm won't help. The first stage is that the status of the TruPortn entry goes UNKNOWN. This is when sacadm gives the error message. Kill sac to respawn and then do a sacadm -r -p on the TruPortn device. This puts sac back in error but when sac has been killed and respawned the TruPortn entry has been removed. Doing a sacadm -a -p for the TruPortn puts it back in the sacadm list but it unusable.
